Embryology of the CNS Flashcards
when does the cranial neuropore form
26
when does the caudal neuropore close
28
what are the three layers of the developing neural tube
ependymal layer
mantle layer
marginal layer
which layer of the developing neural tube develops into the gray matter
mantle layer
which layer develops into the white matter
marginal layer
the mantle layer divides into
alar and basal plates
basal plate is
motor
alar plate
sensory
failure of cranial neuropore to close results in
anencepahly
what are the three basic regions of the adult brain
forebrain
midbrain
hindbrain
prosencephalon divides into
telencephalon and diencephalon
rhombencephalon
metencephalon
mylecephalon
components of myelencephalon
medulla and lower 4th ventricle
components of metencephalon
pons, cerebellum, and upper 4th ventricle
components of mesencephalon
midbrain and cerebral aqueduct
components of telecephalon
cerebral hemispheres and lateral ventricles
components of diencephalon
thalamus, hypothalamus, epithalamus, subthalamus, and third ventricle
craniopharyngiomas
diabetes, pituitary problems persistent rathke’s pouch
major visual impairment, developmental delays and chronic headaches results in
craniopharyngiomas
oder of innervation along the neural tube
GSE, GVE, SVE, GVA/SVA, SSA, GSA
what week becomes sulci and gyri
30 weeks
when does myelination begin
3rd trimester and continues after birth
Band Heterodopia
double cortexism, extra band of what matter
what is schizencephaly
large clefts in the brain
absence of the cerebellum vermis
dandy walker syndrome
recurrent seizures/ not as many sulci or gyri
lissencephaly
herniation of the cerebellum
arnold chiari syndrome
